Question

我试图从配置单元加载表。 我正在使用Hcatalog。

我登录到蜂巢使用

pig -useHCatalog 

我出口从蜂巢和Hadoop

几乎所有的罐子我想这个命令也

ant clean jar -Dhadoopversion=23' 

它是一个版本不匹配的问题？

我使用Hadoop 2.0.0 cdh4.5.0和猪0.12.0-SRC

请帮助

Answer 1

是的，这是一个兼容性问题。 JobContext is a class Hadoop中2.X

：

在Hadoop中的1.x
• JobContext is an interface

您可以看到Hadoop的2不被列为兼容猪0.12：

Requirements 
Mandatory 

Unix and Windows users need the following: 

Hadoop 0.20.2, 020.203, 020.204, 0.20.205, 1.0.0, 1.0.1, or 0.23.0, 0.23.1 

http://pig.apache.org/docs/r0.12.0/start.html

Answer 2

您可以尝试构建Hadoop 2.x ve Pig的过去也是

ant clean jar-withouthadoop -Dhadoopversion=23
